* fec_imx: Implement reset timeoutAndrey Smirnov2016-03-171-1/+6
| | | | | | | | | | Don't wait for more than one second for IP block to finish resetting. If the block is dead it makes more sence to continue execution in hopes that the rest of the processor is fine, rather than spin indefinetly inside of the fec_probe function Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* fec_imx: Deallocate I/O resources if probe failsAndrey Smirnov2016-03-161-5/+9
| | | | | | | | | | Add a proper check for I/O memory resource allocation failure and replace dev_request_mem_region with dev_request_mem_resource so it would be possible to correctly deallocate device's I/O resources when probe fails.

* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-1/+5

E.g. see 'git grep -A 4 of_device_id drivers/' output: drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = { drivers/ata/sata-imx.c- { drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci", drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6, drivers/ata/sata-imx.c- }, { Here is of_device_id struct in linux kernel v4.0: struct of_device_id { char name[32]; char type[32]; char compatible[128]; const void *data; }; Changing of_device_id.data type to 'const void *data' will increase barebox' linux kernel compatibility and decrease number of 'unsigned long' casts.

| | | | | | | | | | | | | | | | | | | | While this makes sure that the phy fixups are applied even if networking is not used on i.MX6, this patch due to latest phy changes causes the startup of barebox delayed until we have a link on the i.MX fec. Revert it for now and look for a better solution later. This reverts commit 3a17af33c01fd066ab3939c8218037c87ba26eed.

* | net fec: connect phy at probe timeSascha Hauer2012-10-301-13/+30
|/ | | | | | | | | | | | Several i.MX boards (all i.MX6 boards) need to do some adjustments to phy registers. If barebox itself does not use network, networking won't work in the kernel if the kernel does not have the fixups. Connect the phy at probe time so that these tweaks are done during probe so that the kernel works without phy register tweaks. Also this has the effect that the phy device is present and introspectable without doing fake network transfers beforehand. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
